Since last summer’s hack of a connected Jeep, auto cyber-security has become a red-hot issue, one that automakers cannot avoid. And with connected cars expected to be a durable trend, the need for over-the-air software and updates that cannot be hacked is crucial. Semiconductor company Rambus has developed a new solution that delivers “one-time single-use keys that are unique to each vehicle,” to minimize vulnerability. The CryptoManager platform can authenticate and encrypt code updates via a secure channel between the car and the cloud. According to Rambus, the system is like closing the door of a house—an initial necessary step for car makers.
